Abstract
A socket and fabrication method provide enhanced performance. The socket includes a base, and a plurality of signal contacts disposed within the base. A grounding fence is also disposed within the base such that the grounding fence laterally isolates the signal contacts from one another. The use of a grounding fence therefore enables elimination or significant reduction of ground contacts and therefore provides more signaling opportunities for a given amount of real estate.
Claims13
A socket comprising:
- a base;
- a plurality of signal contacts disposed within the base;
- and
- a grounding fence disposed within the base, the grounding fence laterally isolating signal contact pairs from one another to support differential signaling and laterally isolating individual contacts from one another to support single-ended signaling, the signaling to occur between a semiconductor package connected to the socket and a printed wiring board (PWB) connected to the socket.

A socket comprising:
- a base;
- a plurality of signal contacts disposed within the base;
- and
- a grounding fence disposed within the base, the grounding fence laterally isolating pairs of signal contacts from one another to support differential signaling and laterally isolating individual contacts from one another to support single-ended signaling, the signaling to occur between an adjacent semiconductor package and an adjacent printed wiring board (PWB);
- wherein the grounding fence includes a plurality of electrically conductive wall members and an interconnection structure coupled to one or more of the wall members, the interconnection structure enabling electrical contact between the grounding fence and a ground plane of the PWB;
- said wall members having surfaces defining a plurality of contact apertures such that the contact apertures encompass the signal contacts, and the interconnection structure including a plurality of metal feet extending from a board side of the grounding fence, the metal feet have a spacing that is less than a quarter wavelength of a predetermined operating frequency.
3 more elements
A socket comprising:
- abase;
- a plurality of signal contacts disposed within the base;
- and
- at least one grounding fence disposed within the base, the at least one grounding fence laterally isolating signal contact pairs from one another to support differential signaling and laterally isolating individual contacts from one another to support single-ended signaling, the signaling to occur between a semiconductor package coupled to the socket and a board coupled to the socket.
